81 is what percent of 94 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 94 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 94, so we can write it down as 100%=94.
4. We know, that x% equals 81 of the output value, so we can write it down as x%=81.
5. Now we have two simple equations:
1) 100%=94
2) x%=81
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=94/81
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 81 is what percent of 94

100%/x%=94/81
(100/x)*x=(94/81)*x       - we multiply both sides of the equation by x
100=1.1604938271605*x       - we divide both sides of the equation by (1.1604938271605) to get x
100/1.1604938271605=x
86.170212765957=x
x=86.170212765957

now we have:
81 is 86.170212765957% of 94
